.This invention relates to tools and method of making the same, and with regard to -l certain more specific features, to diamond tools.

Among the several objects of the invention may be noted the provisio'nf'of a simple and durable tool construction; and the provision l5 of an effective and inexpensive method of making a tool. Other objects will be in lo part obvious and in part pointed out hereinafter.

'The invention accordingly comprises the features of construction, steps and sequence ofl steps, combinations of elements and arrangements of parts, which are exemplified in the description hereinafter in connection with the accompanying drawings, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, in which isillustrated diagrammatically one of various possible embodiments of the invention, Fig. 1 is a central sectional elevation of a piece of glass tubing and steel rod, and 215 a artly constructed tool in the tubing;

Fig. 4 is a similar view of the holder,

when the contents of the glass tubing of 2 have been pushed into said holder;

Fig. 6 is an elevation of the completed Similar reference characters indicate corresponding parts throughout the several views of the. drawings.

. 1 to 4 of the accompanying drawings, there -is illustrated at 1 a piece of glass tubing,

into the central bore 3 ofI which has been inserted a steel rod 5, to close one end of the i 415 tubing. y

' Into the other end of the tubing has been,l

.inserted a small quantity of amalgam 7. This amalgam is preferably ofthe following composition by weight: powdered gold 1 part; powdered silver 9 parts; mercury 28 parts; rubbed together to give a mixture 'of about the consistency of putty. The powdered silver may be prepared by pre- Referring now more particularly to Figs.

cipitating it from a solution of silver nitrate with a'strip of sheet copper. The powdered 55 gold maybe prepared in similar manner by usinga solution of auric chloride.

A diamond 9 has been set into the amal gam 7, with a pair of long pointed tweezers (not shown).

As indicated in Fig. 2, more amalgam and 1 additional diamonds are alternately inserted into the tubing, until the tool is of the re-` .quired length. The amalgam at the end ofv the tubing should preferably cover the right hand diamond 11;'and all of the diamonds should be entirely embedded in the amalgam. I A tool holder of the type shown at 13 inFig. 8 is preferably used. This holder has a threaded hole 15 in it,` of the diameter of the bore 3 inthe glass tubing 1.

The slug of amalgam and embeddedl dia.` monds shown'in Fig. 2 are placed in linewith `the hole 15 in the holder 1.3, and by 75 means of the rod 5 the slug of amalgamV and.l diamonds are pushedv into said .hole lin the holder, to the posi-tion indicated in Fig. 4.

, A steel rod 17 (Fig. 5) is then fitted into the hole 15 in the holder, one end of the rod 17 resting on the amalgam, the other end of said -rod being pressed by a cla-mp 19, or other suitable device, with such a force as lwill put the plastic amalgam under a' substantial pressure.' A pressure of five thousand. pounds tothe square inch has been found satisfactory. .This will force out apart of the mercury from the amalgam.

While the clamp thus-maintains pressure on the amalgam, the tool is heated to a barely visible red heat, by means such as a burner indicated conventionally vat 20 in Fig. 5. This drives `off substantially all the mercury in the form of vapor. 'The amalgam shrinks so thatthe clamp has to be tightened from time to time.. The gold and silver alloy does not melt, but is com ressed so as to conform to the contour of t e diamonds and to the threads in the holder. After the combinedy heating and pressure step has been concluded, and after the tool has cooled, the.

tool is cut olf to as to expose a suitable por`- tion of the surface of the outermost diamond. A plane for such cutting isl indicated in dotted lines at 21 in Fig. 5, and vtheflnished tool is illustrated in Fig. 6.

The tool is now ready for use for the various purposes to which diamond tools are adapted.

As the outermost diamond wears awa the cut off successively to expose the'other diamonds that are This construction permits-the utilization of quite small diamonds.
